PILGRIM TYPEWRITING MACHI-NE Filed July 24, 1950 4 Sheets-Sheet 4 J m w WITNESS ATTORNEY Patented Dec. 25, 1934 UNITED STATES TYPEWRITING MACHINE I George James Munson Pilgrim, Thornton Heath, Surrey, England, assignor to Remington Typewriter Company, Ilion, N. Y., a corporation of New York Application July 24, 1930, Serial No. 470,320 In Great Britain January 30, 1930 so Claims.

My invention relates to typewriting or like machines and more particularly to means for aiding in quickly introducing and collating work sheets in the machine and for simultaneously feeding such collated sheets if desired.

The main objects of my invention, generally stated. are to provide comparatively simple yet highly efiicient mechanism of the character specified which may be employed in various kinds of billing operations; by whichvarious features or devices of the construction may be automatically controlled; in which an improved line indicating device is automatically shifted into and out of position for use; in which. various work i5 sheets may be rapidly introduced into the machine and quickly adjusted therein in proper correlation with. another prew'ously introduced sheet; and by which various work sheets may be introduced rearwardly intothe machine from in front of and beneath the platen after another or other previously introduced sheets have been inserted into the machine fromthe rear of and beneath the platen.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularly pointed out in the appended claims. 80 In the accompanying drawings wherein like reference characters indicate corresponding parts in thedifierent views:-

Fig. 10 is a like view including additional parts and showing the parts disposed in an intermediate position between those positions which are indicated in Figs. 8 and 9.

The present invention was devised-to attain some of the same general ends as the construction disclosed in the patent to Frederick A. Hart, 1,650,351, dated Nov. 22, 1927, and may be regarded as an improvement thereon.

I have shown my invention in the present instance embodied in a Smith Premier typewriting machine in which the devices of rmr invention may be readily incorporated without materially modifying the existing structural features of said machine. It will be understood that said machine is a front strike typewriting machine in which the platen is fixed against movement from printing position.

The frame of the machine includes a top plate 1 on which fixed carriage rails 2 and 3 are-supported by brackets 4 in the usual manner. Said rails are provided with oppositely grooved race:- ways to receive crossed bearing rollers 5 which also are received in race-ways in a cross bar6 of the carriage. In this manner the carriage is supported'at the rear thereof for traveling movement from side to side of the machine over the top plate 1.

The carriage includes end bars 7 and 8 which are secured to and project forward from the rear cross bar' 6 and have bearing openings therein for the platen shaft 9 by which a cylindrical platen 10 is supported. The usual line spacing mechanism and finger wheels (not shown) are employed for turning the platen. I

A paper table 11 is supported in the rear of the platen to aid in directing forwardly introduced work sheets to the rear of and beneath theplaten.

Forwardly extending arms 12, each of which forms part of a bracket 13 or 14 fixed to the carriage in the usual manner, constitute means by which a supporting bar (not shown) for vertical tctalizers of the "computing mechanism is connected with the carriage. l g

Upwardly and rearwardiy moving typebars, a fragmentary portion of one of which is shown at 15 in Fig. 1, strike against the front of the platen of the paper thereon. A line a in the different figures represents the printing line or a line with register. The type bars in moving to printing position coact with a type bar center guide 16 'of to brackets 21 provided with set screws 22 by which the deflector may be fixedly connected to a rock shaft 23. A rocking of this shaft is effective to move the deflector from the Fig. 1 to the Fig. 2 position and vice versa. The rock shaft 23 carries a crank arm 24 at one end thereof which is fixedly connected to the shaft by a set screw 25, thus enabling the crank arm to be secured in different v adjusted positions to the shaft. A forwardly projec'ting link 26 is pivoted at its rear end, as at 27, to the crank arm 24 in order to automatically effect a movement of the deflector down from the Fig. 1 to the Fig. 2 position and up again, as will hereinafter more clearly appear.

In the present construction I provide a plurality of flexible or resilient work sheet supporting and guiding bands 28, two being shown in the present instance. These bands are provided to cooperate with the platen 10 to aid in supporting, guiding and feeding one of the work sheets, L, to and around the platen as such work sheet is introduced from the rear thereof. Each of these bands 28 is secured at its upper rear end by bolts 29 and nuts 30 to the upper horizontally disposed portion of the paper table 11. The bands 28 extend from the attached ends thereof parallel with the paper table 11 and around and concentric with the platen and up in front of and above the platen where the free ends of the bandsbear against a cross bar 31 fixed to the carriage and extending from side-to-side thereof above the platen. These bands are slightly resilient and bear against the platen with suflicient force to snugly maintain a work sheet L which is introduced into the ma- .chine from the rear of the platen andbetween said bands and platen, in contact with the platen and cause the sheet to be effectively fed therewith when the platen is rotated.

The cross bar 31 is secured to the carriage by bracket arms 32 carried thereby, said bracket arms being secured by set screws 33 to a cross rod 34 attached at its ends to the end plates 7 and 8 of the'carriage. The cross bar 31 also constitutes a support for a second paper table 35, the front face of which is maintained substantially tangential to the platen at the front portion thereof. This paper table constitutes'a support for a work sheet B that is introduced into the machine from in front of the platen and is directed downwardly and rearwardly beneath the platen to the deflector 20, as indicated in Figs. 1 and 2.

In order to facilitate such an introduction of the sheet B into the machine, I have provided a second deflector plate 37 that is automatically moved from the ineffective position shown in Fig. 1, to the effective position shown in Fig. 2, where the lower end of the deflector 3'7 is moved into cooperative relation with the deflector 20 to practically form a continuation thereof for directing the lower end of the work sheet B into the machine past the type guide and ribbon vibrawhich the bottom ends of the printed characters torand into the channel 38 between the deflector 20 and the platen. In this movement of the deflector 3'? to and from effective position, it moves past the printing line and must necessarily be moved from its effective position, shown in Fig. 2, to the ineffective position shown in Fig. 1, before the type bars can reach the printing position. This operation of the deflector 37 is automatically controlled, as will hereinafter more clearly appear.

It will be understood that a carbon sheet C, preferably substantially coextensive with the work sheet L is simultaneously introduced into the machine therewith and is employed for making a manifold copy of the work written onthe work sheet B. If desired, a carbon sheet coextensive in size with the bill sheet B may be introduced and withdrawn with the latter instead of employing the carbon sheet C in the manner indicated.

In order to facilitate a proper positioning of both the ledger sheet L and bill sheet B in the machine, I have provided a line indicator which is in the nature of a thin flat sheet metal strip 39 that extends longitudinally throughout the length of the platen and is connected at its ends to depending portions 40 of two arms 41 and 42. These arms at their forward ends are secured by set screws 43 to a rock shaft 44 that extends across the carriage from side-to-side thereof and is supported in bracket arms 45 fixed to the carriage. It will be understood, therefore, that the line indicator 39 receives a direct up and down motion to and from indicating position around the center of the shaft 44, the line indicator being shown in its indicating position in register with the printing line a in Fig. 8, and in the lowered, ineffective, position in Fig. 7. Means are provided for automatically controlling the line indicator 39, as will hereinafter more clearly appear.

I have provided means whereby the only paper feed rollers, 46, which are brought into cooperation with the platen are mounted for movement from the effective position represented in Fig. 1, to the ineffective position, indicated in Fig. 2 and vice versa. It will be observed that when the feed rollers 46 are in the effective position they are disposed above the printing line a and are adapted to coact with the work sheets B and L and the interposed carbon sheet C, only above the printing line. As clearly shown in Figs. and 6 the feed rollers 46 are mounted on a supporting shaft or spindle 47, each end of which receives a bearing in an arm 48 provided at its forward end with a hub 49 supported on a rock shaft 53. Each arm 48 carries a pin 50 by which one end of a coiled spring 51 is connected to the companion arm 48, the opposite end of said spring being anchored to a collar 52 secured by a set screw 52 to the rock shaft 53. Each hub 49 is slabbed off at one side thereof, as indicated at 54, to provide a contact face for cooperation with a corresponding slabb'ed ofi portion or contact face 55 of a collar 56 secured by set screws 57 to the rock shaft 53. There is a slight lost motion provided between the contact face 55 of each collar 56 and the contact face 54 of the associated hub 49 with which it coacts. The construction is such that each arm 48 is provided with an individual spring 51 which exerts its individual force on the companion arm 48, as will presently appear, and that the effective force of each of said springs may be varied by a rotative adjustment of the companion collar 52 to different set positions around the shaft 53. When the shaft 53 is rocked, both arms 48 and the springs 51 will turn bodily therewith, and but a slight spring pressure is exerted by each of the springs 51. When, however, the shaft 53 is rocked a sufficient distance to bring the feed rollers 46 against and arrest them by the platen while a continued motion is given to the shaft, the effect will be to turn the collars 52 while the arms 48 are maintained fixed against movement, thus winding, stressing or tensioning the springs 51 and applyingthe force thereof against the arms 43 and the feed rollers 46 carried thereby. The extent of this continued motion of the shaft 53 after the feed rollers are brought to bear against the platen, corresponds to the extent of lost motion provided for between the collars 56 and the hubs 49. This is .sufllcient, however, to effectively tension or stress the springs 51 and cause them to exert suflicient pressure on the feed rollers to maintain the latter against the work sheets with sufficient force to effectively feed such sheets when the platen is turned.

Fig. 3 represents the positions of the parts when the feed rollers 46 have been brought to bear against the work sheets without tensioning the springs 51. At this time the feed rollers bear against said work sheets wholly by the weight of the parts, free from any pressure of the springs 51. This is in order that the ledger or bill sheet, and more particularly the latter, may be adjusted relatively to the line indicator while the sheet is held by thefeed rollers 46 in its position of adjustment, but without suflicient pressure to interfere with the adjustment of the sheet. When the work sheets have been properly adjusted and correlated the rock shaft 53 is given a further rocking motion to tension the springs 51 and effectively apply a feeding pressure to the feed rolls 46. Means are provided for locking the rock shaft at the end of this movement by which the springs are tensioned, in order to prevent a return of the rock shaft under the reaction of said springs. Such locking means and the means for controlling the rock shaft 53, as well as other of the devices previously described, will now be referred to.

The rock shaft 53 constitutes the main actuating shaft by which the various devices of my invention, including the feed rollers 46, the bottom deflector 20, the'line indicator 39 and the front deflector 37, are controlled. This shaft 53 is mounted at its ends in bracket plates 58 and 59 secured to the carriage frame, and near the right-hand end thereof said shaft is provided with a crank arm 60 that terminates in a finger piece 61 by which the shaft may be actuated. when the arm 60 is swung forward to the Fig. 2 position, the parts will remain in such position with the ineffective position giving free access to the front of the platen for the introduction of a bill sheet B and when desired, the accompanying carbon sheet. When the arm 60 is turned rearward to the Fig. 3 position, the weight of the parts alone will maintain the feed rollers 46 against the work sheets on the platen, free from pressure of the springs 51. When, however, the arm 60 is further depressed to the Fig. '1 position, this results by the further turning of the rock shaft 53 intensioning the spring 51 and applying the eflective force thereof on the feed rollers 46. In, order to lock or latch the finger piece 61 and the rock shaft 53 against the reaction of the springs 51, and maintain the force thereof against the feed rollers, I have provided a latching means which will now be described.

Fivoted at 62 on the outer side of the arm 60 is an angular or bell crank lever 63 provided at the end of one of its arms with a finger piece 64, as best shown in Figs. 2 and 3. The other arm 63" of the lever 63 has a locking pawlor latch 65 pivoted thereto at 66, said latch having a hooklike engaging end 67. Extending laterally from. the member 65 are two lugs or stops 68 and 69 that are on opposite sides of and coact with the arm 63' to limit the motion of the latch relatively to said arm. A leaf spring 70 is fixed at one end by screws 71 to the lever 63 and bears at its free end against the lug 69 to normally maintain the latch member related to the arm 63 as shown in Fig. 2. Referring more particularly to Figs. 5 and 6, it will be. seen that a coiled spring 72 surrounds the pivot 62 by whichthe lever 63 is mounted on the crank arm 60, the other end of said spring being fixed to the lever 63, as indi-' 'cated at '75. The force of this spring is therefore relative movement of the lever 63 is limited by a pin 74 carried by the arm 60 passing into a slot 76 in said lever 63. With the aid of this construction a depression of the finger piece 61 from the Fig. 3 to the Fig. 1 position will result in tensioning the springs 51 of the feed rollers and in maintaining said pressure on the feed rollers so long as the finger piece 61 is maintained depressed by the operator. As soon, however, as the operator releases pressure on the key 61 the pressure of the springs 51 will be released. When the operator desires to maintain indefinitely the force of the springs 51 on the feed rollers, it is merely necessary to depress the finger piece 64 from the Fig. 3 to the Fig. 1 position. This will result in moving the crank arm 60 down through the pin and slot connection 74, 76, after the force of the spring 72 is overcome. The effect of thus moving the crank arm 60 is to tension the springs 51 exactly as such result is effected by depressing the key 61. In depressing the key 64 from the Fig. 3 to the Fig. 1 position the lower end portion of the latch 65is brought to bear against the front fiat face of a part 77- of the frame of the carriage. The effect of this is to cause a slight displacement of the latch 65 around its pivot 66 and against the force of the spring 70. As soon as the bill of the hook-like end 67 of the latch passes below the lower edge of the member 77, the spring 70 becomes effective to turn the latch 65 on its pivot 66 to engaging position, shown in Fig. 1, and the parts will remain locked in this position, the reactive force of the springs 51 holding the latch engaged under the part '77.

When it is desired to release the latch 65, it is merely necessary to press down on the key 61. The effect of this is to'release the locked latch from the reactive force of the springs 51. The spring "12 then becomes effective to move the latch on its pivot 66 and withdraw the hook-like member of the latch from beneath the coacting looking member 77. The operator will then release the depressed key 61 and the parts will return to the Fig. 3 position, releasing the rollers from a spring pressure.

In addition to controlling the feed rollers in the manner described, the finger piece 61 also controls the movement of the bottom deflector 20 from the Fig. 1 to the Fig. 2 position and vice versa. Such means will now be described.

The link 26 (see Fig. 3) is a two part link, the members of which are united by a thread.- ed connection at 78 and the front member is slotted at 79 to receive the shank of a headed screw or pin 80 received at its threaded end in a tapped opening in a disk 81. This disk has a hub 82 (see Fig. 6) tapped .to receive a set screw 83 by which the disk is secured to the rock shaft 53. Due to the pin and slot connection-80, 79 between the link 26 and the shaft 53, the deflector 20 will remain unaffected by the turning of the shaft 53 until just prior to the time that the arm 60, in swinging forward, reaches the Fig. 10 position. When such position has been reached, the pin 80 has reached the forward end of the slot 79 and has shifted the link 26 forward and moved the deflector 20 down away from the platen in order to create an enlarged, unobstructed, channel 38 between said deflector and the platen for the free passage of a rearwardly introduced work sheet B, and an accompanying carbon sheet if such be used instead of the carbon sheet C. It will be understood that the bands 28 hold the previously introduced ledger sheet L snug against the platen so that it offers no obstruction or obstacle to the ready backward introduction of the bill sheet B into position in the manner described.

As the finger piece 61 is moved rearward after the introduction of a sheet B, the pin 80 will be carried rearward enabling a spring 84 (Figs. 6 and 10) to elevate the.d eflector 20 to a position where it will bear lightly against the sheet B and press it lightly against the under sides of the metallic bands 28. The spring 84 surrounds the rock shaft 23 and is connected at one end to one of the brackets 21 and is connected at the other end to a fixed part 85 (see Figs. 1 and 10) of the carriage.

The rock shaft 53 also controls the movement of the line indicator 39 to and from effective, or indicating position, as will now be pointed out.

From an inspection of Fig. 4- it will be seen that one of the supporting arms, 41, for the line indicator 39 has one end of acontractile returning spring 86 connected thereto, at 87. The other end of this spring is connected to a pin 88 that projects from one side of the adjacent bracket plate 58. The force of this spring is exerted to move the arms 41 and 42 upward and bring the indicator 39 to the line indicating position, as shown in Figs. 3 and 8. The parts are arrested in their movement to such position by an adjustable screw stop 89 threaded into a fixed part of the carriage or bracket plate 58 and cooperating at its lower end with the arm 42, as shown in Fig. 8. The arm 42 carries an upwardly extending finger 90 and extends into the path of a cam 91 formed as a depending part of the crank arm 60. As

the arm 60 is moved forward from the Fig. 8'

to the Fig. 10 position, the cam 91 will be brought into engagement with the upper side of the arm 42, and the finger 90 which is formed thereon, to depress the line indicator 39 to the ineifective Fig. 10 position, and hold it in such position. As the indicator 39 reaches its lowermost position under control of the cam, the curved contact faces 92 on the cam reaches and coacts with the arm 42 and acts in the nature of a dwell to hold the indicator in its lowered position during the further forward motion of the arm 60. Such forward movement of the arm 60 is limited by a stop pin 93 on the hub 94 of the arm 60 coacting with a pin 95 projecting from the righthand bracket plate 59, as shown in Fig. 9.

The body portion of'thearrn 60 also is operative on the extreme end of the finger 90 of the arm 42 when said arm is moved backward and downward from the Fig. 8 to the Fig. '7 position, and at this time moves the indicator 39 from the indicating to the ineffective position out of the path of' the types. This motion of the arm 60 takes place as said arm is moving from the Fig. 3 to the Fig. 1 position, to tension the springs 51 and apply the force thereof to the feed rollers 46, as hereinbefore described. Should the depression of the arm 60 just referred to be brought about by a depression of the key 64, then said springs 51 will be looked under tension and the line indicator will be held depressed until the latch 65 is released in the manner hereinbefore pointed out.

In addition to the foregoing operations brough about by a rocking of the shaft 53, or the arm 60 connected therewith, the movement of the front deflector 37 to and from efiective position is brought about as will now be described.

As best shown in Figs. 2, 4 and 5 the upper edge of the deflector 37 is bent around and secured to a shaft 96 supported at its ends for pivotal move ment in bearings 97 in supporting arms 98 secured to a rock shaft 99. Fixedly connected to the rock shaft 96 near one end thereof is a crank arm 100; a set screw 101 being employed to adjustably connect the hub of said crank arm to the shaft. The upper end of the crank arm 100 is provided with a headed screw or pin 102, the shank of which is received and works in an arcuate slot 103 in a link 104. This link is pivoted at 105 to a crank arm 106 mounted on the rock shaft 53. From the foregoing it will be understood that the deflector 37 is adapted to receive a bodily pivotal motion around the rock shaft 99, and also may receive a pivotal motion around the shaft or pivotal center 96 under control of the link 104. The construction and arrangement of the parts are such that the deflector 37 may receive a movement from the ineffective, normal position indicated in Fig. 1, where it rests on soft rubber buffers 37 on the shaft 99, to the position indicated in Fig. 10. When this last mentioned position has been reached, the pin 102 will have reached the rear end of the slot 103 in the link 104, thus from this point on controlling the motion of the deflector 37 around its pivotal center 96. A further movement of the deflector 37 from the Fig. 10 position to the Fig. 4, effective position, is a direct downward motion substantially tangential to the platen to clear the type guide 16 and ribbon vibrator 18 and bring the deflector 37 into cooperative relation with the bottom deflector 20, which at this time has been moved away from the platen, as indicated in Fig. 2. The parts at this time are conditioned to receive a rearwardly introduced bill sheet B into the machine and into the channel 38, as shown in said flgure.

The following are the instrumentalities by which the supporting and controlling members for the deflector 87 are actuated to effect the movements just described.

Referring more particularly to Fig. 1 it will be seen that the rock shaft 53 near the right hand end thereof is provided with a gear wheel 107 fixed to the shaft by means of set screws 108 (Fig. 6) that are received in tapped openings in the hub 109 of said gear wheel. The gear wheel 10'1 meshes with an idler 110 supported on a headed pivot screw 111 supported on the right-hand bracket plate 59. This idler. 110 meshes with a second idle pinion 112 supported on a pivot screw 112 secured to the bracket plate 59. The idler 112 in turn meshes with a gear 113 secured to the shaft 99 on which the arms 98 are secured. It-

will be understood, therefore, that a rocking motion of the shaft 53 will, through the gearing 107, 110, 112 and 113 rock the shaft 99 and cause the arms 98 to be vibrated forward or back from the Fig. 1 to the Fig. 2 position and vice versa. The pivotal motion of thedefle'ctor 3'1 around its pivot 96 is controlled, as hereinbefore indicated, by the I link 104 connected to the crank arm- 106 operatively connected to the rock shaft 53.

The operative connection between the rock.

shaft 53 and the crank arm 106, by which the link 104 is controlled, is effected in the following manner.

The crank arm 106 is loosely mounted on the I capable of rotative adjustment on the shaft to different set positions to regulate the force of the spring on the arm 106. The force of the spring 116 normally maintains the arm 106 against a stop pin 119 projecting from the bracket 58, as

;;shownin Fig. 10 and in dotted lines in Fig. 3.

The force of the spring 116 is suiflcient to hold the arm 106 in the normal position until the parts reach the 10 position. It will be observed that at this time the pin 102 has reached the rear end of the slot 103 and caused the de- 'arm- 100 positively moving down with the arms 98 will actuate the link 104 and'arm 106 against the force of the spring 116. As the parts are brought to the Fig. 4 position, an adjustable screw stop 120, carried by one of the arms 98, will reach contactive engagement with the arm 100 and arrest and positively hold the deflector 37 against pivotal movement in one direction around a the pivotal center 96, whereas the force of the spring 116 tends to hold the arm 100 against said stop 120, thus assuring the maintenance of the deflector 37 in proper relation to the platen and to the deflector 20.

As the arm receives a rearward movement from the Fig. 2 position, the spring 116 will be effective to turn the arm' 106 until the latter reaches the stop 119, as indicated in Fig. 10. This arrests the arm 106 andlink 104, and in the further continuedv rearward and downward movement of the arm 60 to the Fig. 3 or Fig. 1 position, the pin 102 will move freely along the slot 103 while the deflector37 is returned to its ineffective, Fig. 1, position. v

By reason of the pivotal movement of the deflector 37. around two centers 99 and 96 and the controlling means described, said deflector may be moved from the ineffective position shown in Fig. 1, remote from the front face of the platen,

rearward to the Fig. 10 position over the ribbon.

" guide and vibrator and withoutthe necessity of' moving the vibrator down in order that the deflector 37 may clear it.

From the foregoing description it will be understood that the forward movement of the arm 60 from the Fig. 1 to the Fig. 2 position results in moving the feed rollers 46 from the platen to an ineffective position remote from the platen, where the rollers give free access to the front of the platen for withdrawing the written bill sheet and introducing a new one after the ledger sheet has been removedand a new one has been introduced and accurately positioned. This same movement of the arm v60 also results in lowering the line indicator 39 to the ineffective position; in lowering the bottom deflector away fromthe platen to provide an enlarged, unobstructed channel 38, and in moving the front deflector 3'7 from an ineffective position to a position where it is brought into cooperative relation with the lowered deflector 20 to aid in effecting a backward introduction of a bill sheet B to and beneath the platen fromin front thereof.

After the worksheets have been inserted and correlated with the aid of the line indicator, arearward movement of the arm 60 to the Fig. 3 .position will result in moving the feed rollers 46 against the work sheet, the weight of the parts holding the feed rollers against said sheets. This same movement of the arm 60 results in withdrawing the deflector 37 and moving it to inefiectiveposition; in elevating the deflector 20 against the bill sheet and in elevating the line indicator 39 to indicating position. The bill sheet B at this time is held against accidental displacement by the feed rollers 46 that bear against it but not with suflicient force that said sheet cannot be given a final accurate adjustment with reference to the line indicator 39 which is in eflective position at this time. This flnal adjustment of the bill sheet having been effected,

the flngerpiece 64 is depressed to place the feed rollers 46 under ,the tension of the springs 51 and lock the parts in such condition. The depression of the finger piece 64 also results in forcing the line indicator 39 down to and in holding it in the ineffective position. The machine at this time is conditioned for writing and the operator may proceed with the writing, making a manifold copy on the ledger sheet L through the interposed carbon sheet C .of all matter written on the bill sheet B, the latter of course being produced by the operation of the type faces on the usual inking ribbon 19 carried by the ribbon vibrator 18.

Suitable side edge gages for the ledger sheet L and for the bill sheet B may be provided. In

the present instance I employ the usual side edge .the nature of a plate or blade that extends up from' the paper table 11 at substantially right angles thereto. This gageis adapted to coact with the left-hand side edge of the ledger sheet inserted in the rear of the platen. I also provide a side edge gage 122 (see Figs. 3 and 6) by extending an upright flange from the left-hand 'side of the paper table 35, the plane of the gage 122 being at substantially right angles to the plane of said paper table 35. r

While I have referred herein to the ledger sheet L and the bill sheet B entered into the machine in a given manner it will be understood that such reference is by way of example only,

and that the machine is capable of a wide range of uses both in billing operations and in other sheet which may remain in the machine. I do not deem it necessary to specifically describe the Various uses to which the machine may be put, it
